The computer aided design of the Sinking 3D Magnum features a tough polycarbonate body, 3X strong treble hooks and through wire construction making it the most durable trolling lure of its type on the market. Yo-Zuri's proprietary and patented Internal 3D Prism Finish, coupled with our internationally patented Color Change technology, makes these baits stand out in any fishing condition!!! They are designed to be fished with a crimp, loop knot, cable or single strand wire, to give the bait the freedom to swim correctly. 3D Magnums are deadly on a number of offshore species including Tuna, Wahoo, Dolphin and King Mackerel, just to name a few. This versatile trolling lure can be pulled from 4-9 knots with a wide swimming action and runs true out the box, no tuning necessary!
